'Holy Spirit' in the Bible

And I knew him not; but he that sent me to immerse in water, said to me, On whom you shall see the Spirit descending and remaining, this is he that immerses in the Holy Spirit.

But this he spoke of the Spirit, which those who believe on him were about to receive; for the Holy Spirit had not yet been given, because Jesus had not yet been glorified.

But the Paraclete, the Holy Spirit, whom the Father will send in my name, he shall teach you all things, and bring to your remembrance all things that I have spoken to you.

And when he had said this, he breathed on them, and said to them: Receive the Holy Spirit.
